@faker Hence, this content is dual licenced de facto. It never was exclusive licencing, I clarified that in my answer. I notice however, that the stackexchange network barely respect other people copyrights, especially for posts copy-pasting non-free content.

You can also do the reverse and get the service tag from the express service code by swapping the 10 and the 36 in the PHP code.

Thanks I didn't know those. It makes you dependant of a webservice you don't master though. This can be a problem if you're in a situation where you must contact the support because you don't have Internet access anymore.
